Yes, I've tried several.
In fact, there are 10 different versions I've come across.
But none of them contain valid keys, although I'm sure some of them have working software. The Vianix files include a key editor so if you can get hold of the keys, you're ready to go...
My misunderstanding m8! Thought the question was for VIA2 Soooooory ! I have found some who clame to have the keys of the "Yet Unhacked VIA2" and i have tried them, and they where fake . . Regarding the two links above they work perfectly NO CONCERNS. Peace!
